COMBINATION LOCK.

Application filed July 29,

To all whom t may concern Be it known that I, DANIEL J. ODoN NELL, acitizen of the United States, resident of Cleveland, county of Cuyahoga,and State of Ohio, have invented new and useful Improvements inCombination Locks, of which the following is a specification, the'principle of the invention being herein explained and the best mode inwhich l have contemplated applying that principle, so as to distinguishit from other inventions.

My invention relates to locks, and particularly to combination doorlocks.

The annexed drawings and the following description set forth in detail`certain means embodying my invention, the disclosed means, however,constituting` but one of the various mechanical forms in which theprinciple of the invention may be employed.

In said annexed drawings:

Referring to the annexed drawings, in which the same ordinalsrespectively refer to the same element-s in the several views, there areindicated by the ordinals l and 2, Figure l, casing` members securedtogether by pins 3 and adapted to form a housing vfor my improved lock,and also adapted to be positioned inthe door trame 4b. U pon an inside'spindle 5 is secured an operating` knob 4, and upon an outside spindleis secured an operating `knob `e. Secured to the inside face of thecasingelement 1 a plate 23 having` `an annular' outerend member 28within which is `journaled la hollow casting;` 29 having a rectangularhole 29 therethrough, adapted to receive theinner ends of the spindles 5and 7. This casting` 29 is also jeurnaled in the casing member 1 and hasdiametrically opposed ears 30 one of which, the upper one, Figure 2.lies contiguously adjacent the lasing` member 1, andthe lower oit' whichis somewhat spaced trom said casing, member. tllidably mounted in thecasingmemberl on the pin l33 is a tonguebolt having a locking tongue 36and formed at its inner end into a yoke-shaped member with its two `arms3l lying respectively substantially in the same vertical planes `as thetwoears 30 ot the casting Q9,

as plainly shown in `Figure 1, the ends 32 Ot the two arms 31beingrespectively bent inwardly and outwardly over the ears 30 so as tocontact'with the inner faces oi' said ears. A spring` 34 is disposed inthe bolt 35 between the tongue 3 6 and the pin 33 and the stress ol suchspring` is such as normally to hold the tongue 36 in its extreme outerposition. It is evident that the rotation oit the casting 29 inthebearingijs formed bv i the casing member l and the member Q8' willvcause one or the other oit the ears 30 to move the bolt 35longitudinally and move the tongue 36 iinvardly against the action otthe spring 34 so as to pull the tongue l3G trom the door liran'ie. Thispart ot my mechanism is ot standard construction, in so far as thelocking tongue elements are concerned, and is adapted to be utilized inconnection with the inside knob 4 which, it is contemplated, will alwaysbe free to open the door, without the necessity of first working thecombination. In order that this inside mechanism may be retained withinthe door frame `6, l. secure to the inside tace of theii'rame by meansof the screws 43 a plate 43.. Figures 1 and 4, through ywhich anenlarged portion 42 ot the spindle 5 passes, there beingY secured to theinner face of saidplate 43, by means of screws 442, a second plate 44having` a: yoke shaped lower end 44 adapted to seat closely within acontracted. portion 5 ot the spindle 5, and between the enlargedportions 42, Figure l, the yoke portion 44 extending somewhat below thespindle portions ,42, as plainly shown in F igure l. It isevident thatthe construction just described will pre-l vent the inward or outwardmovement through the casing 46 ot the spindle 5.

Referring now to the outside spindle T, which is adapted to be operatedby the knob G, it is intended that the same should lactuate the casting29 and thus the tongue bolt 35, whenever said spindle 'T .can be forcedinto the rectangular hole 29 ytermed in said casting, and that normallyit should beheld out oit the rectangular hole 29in said casing, i. e.,in the position shown in F iguije l. Furthermore, it is contemplatedthat one or any desirable 4number ot' combinations, dependent upontheposition, lengths, etc.,ot` dity'ferent elements, hereinafter `t'ullydescribed,

should be lworked by means ot turningu the knob 6, betere the spindle 7can be forced into or will automatically seek the cgeniugii 29. Thiscombination consists et a certain construction ot cam mechanism whichwill now be described. liietly, this combination mechanism consists ot'a latch which isladapted to keep 'tliespindle I trombeing pushedinwardly or pulled outwardly; a tumbler secured to the spindle i' andadapted, in certain positions and pursuant to certain actua-- tions, telitt the latch to vtree the spindle; and certain elements determiningand causing' the yaction ot the ,operating finger whereby the latter isput in position as it rotates 'with the spindle, which is capable or"turning, te lift the latch toiree the spindle. rThe aforementioned latchis indicated bythe ordinal 9, and tlie same is pivotally mounted on theplate 2 at one end by means oit a pin 19 and. held to said plate atitsother end, i; so tar as any forward movementor any outward movementfrom the plate is concerned` by means ol screw l2 underthe head ot'which said outer end of the latch 9 is adapted to move adjacently theeasingl member 2. This latch 9 is 'formed with an undercut 9 adapted tolit over and closely adj acent to a reduced portion 8, FigureQl. of thespindle 7. By means ol" a spring 11` secured to the inner end ot thelatch 9 and also secured to a screw l1 in the plate 2, the latch 9 isnormally held down tightly to the'spindle portion 8. lnteriorly` of theportion 8 the spindle 7 is formed with a flange and exteriorly @if thespindle portion 8, the spindle T is termed with an exteriorly beveledshoulder 73, Figures l and 29. Rotatably `secured -within the flange 24is an operating inger I18 whose detailed construction is plainly shownin Figures 18 and 19. This operating finger is a wire having bent ends19 and the Vend 2O being bent at an angle otabout forty-live degreesfrom i the angularity of the end 19. For mirposes, which willhereinafter fully be understoochthe end 19 is thin or sharpened portionand the end 2OV is thick ened orblunt. Furthermore, centrally of itsends and also substantially centrally of the iiange 24C, thecperatinglinger 18 is 'formed with athinbody portion 18 having a datI face. Thisconstruction is substantially that created by cutting` away for thedesired distance, `substantially half of `'the material of which thesubstantiallycylindrical body portion'18y is comprised. This is alsoplainly illustrated in Figure 18.

Referring to Figure 20v it will be noted that intermediately the innerend 7 `of the spindle '7 and a floating plate v22V disposed within saidspindle and adjacently the flattened central portion 18 vof' the linger18, 'is a spring 23. Tt is evident that, inasmuch as the finger 18 isfree to turn in the flange 2t,the operating finger will be automatically`turned back into the position' shown in Figure 20, if it is turnedmanually substantially less than ninety (90) degrees, because the plate22 bears against the flattened portion 18 of the finger 18, beingpressed there-- against by reason of the tension of the spring 23, andthe unequal pressure upon the tumbler, atl any angle substantially lessthan `ninety (90) degrees, will turn the finger into the position shownin Figure 20. Vhen the finger 18 is in a position ninety or moredegrees'or, of course, a multiple of ninety (90) degrees, from thatshown in Figure 20, the pressure ofthe plate 22 is distributed *evenlylover the 'surface of the finger 18, Vagainst which it presses, andinduces no turning of the finger 18 in either direction.

Assuming the elements to be those herein- `before described and theiractions such as instruction is such that these results take place.

New, when the `finger 18 turns freely with the spindle 7 so as to haveno effect upon the latch 9, it is evident that the door cannot beopened, Furthermore, it is also evident, that if 'the finger 18 liftsthe latch 9 to free the spindle 7 so that the latter can be movedinwardly, the door can be opened. Certain elements now to be described'form a combination which when worked, in any one of many possiblecombinations, react upon the linger 18 to cause the same to ybe turnedninety degreesV or amultiple thereof, which, in turn,v puts the finger18 into position to lift the latch 9. Unless the whole combinaltion isworked, and unless each element thereof is worked properly, the linger18 will be freed from the restraint imposed with the latch 9 to' liftthe same, These combination elements consistof certain wires 25, 26, V27and L15, Figures 7 to 17, of which l"the wires 25, 26 and27 act to turnthe finger 18 through ninetyfdegrees and the wire 45 acts toturn thesame through a further rninety degrees', that is, into a position 18()degrees from that-shown in Figures 7 and 2O so that the finger can liftthe latch 9. The

`wires 25, 26 and 27 are spring elements secured at one end to theinside face of the casing member 2 and may, if desired, be assisted intending to keep their normal posi- `tions by means of springs, =such asilluscaused by the working 'of the combination.

The wire l5 is a short, substantially uiiyieldable elementalso securedto casing member 2. nworking the combination, the tensions ofthe wires25, 26 and 27 act upon the sharpeiied end 19 of the finger 18 to turnvthe latter, as it rotates with the spindle 7, through ninety degrees,dotted lines, Figure 13, and then the wirel acts upon the sharpened end19 to turnfthe finger through a further ninety degrees, Figure16,\\\vl1e'n the blunt end 2O is then in suoli position as to be able,upon thehturningof the spindle 7, to lift the latch' 9. The varioussteps of `eeeting the aforedescribed result are shown in Figures can beobtained by any desirable inea-ns, such as positioning the knob 6 in acertain position which it is known will cause the combination mechanismto be at the proper starting position, inasmuch as the spindle 7 rotateswith the knob 6 and the linger 18 rotates with the spindle7. In thecombination illustrated in the accompanying drawings, and heredescribed, for purposes of illustration, the spindle 7 is turned so asto bring the fingery 18 `into the position shown in Figure 9. Thisaction 'would be caused by a movement of'tlie knob (5 from right toleft. l't is evident from ll`igure 10 that the sharpened end 19 of thefinger 18 now extends between the` wires 25 and 26, and the pressure andposition of such wires are suoli that the finger 1,8, in vtravellingfrom the position shown in Figure 7 to that shown in full lines, Figure9, has been turned through a fraction of 90 degrees. This is only a'portioii of the first length of travel of the finger 18 or the workingof the lirst number of `the combination, the full length of travel beingindicated by the dotted line position of the finger 18 in Figure 9. Tnthis position, in the combination chosen for illustration, the sharpenedend 19 of the finger 18 has been freed from the wire 25, and the wire 25is pressing against it and preventing it from turning .into its normelposition, i: o, .that ehownin `Figures ..7V and .20. ,Theftensionandposition of this Wire is suoli that although the linger 18 vtendseutolltoally -t'o turn .beek into `the position shown inFigure 7, due tothe unbalanced position of the plate 22, still it is restrainedronil-sodong by o eid .wire 125, The next step is to tunnlthe linger,-18 to the left, TF igurehiinto a position shown in dottedlinesinFigure 1l, ,a `position immediately short ofsaid position beingindicated in full linesfinsnid figure. Duting this notion, the end lQ ofthe linger `first rides uponthe Wire 2 5, nndfthen ridosfnpon the Wire 26, being oontinuously turned .on its exis eothat, :when it reaches theposition ,shown indotted lines in Figure 11,;itrests .upon the W1e27,`being restrained by Vboth of 'the Wires 2end2`, andhes been turnedthroughtho greetelpert otlnnety (9.0) de- `grees fronrthe position showninFigure .7.
